Abstract

The invention discloses a haze particle formation simulator which comprises a combustion furnace, a control console, a growth simulation chamber, a light shield, a sucking pump, a flow meter, a three-way valve with a stop valve, a haze particle collector and an air purifier, wherein the growth simulation chamber is fixed on the control console; the combustion furnace, the growth simulation chamberand the air purifier are connected into a system by the sucking pump; the three-way valve with the stop valve realizes independent operation of a smoke dust source supply channel and a haze particlecollection channel; multiple feeding holes and an exhaust valve are formed in the growth simulation chamber, and the growth simulation chamber is equipped with temperature, humidity, airspeed and light intensity detection sensors as well as a light source, a fan and a supercharging balloon; and a temperature control device, a humidifier and a pressure gage are arranged in the control console. By detecting and regulating the temperature, pressure, humidity, airspeed and light intensity in the growth simulation chamber, the outdoor environment formed by haze is simulated, a research is conductedon formation of single haze particles or a multi-haze particle mixing system, and the haze particle formation simulator has obvious value on treatment of the atmospheric environment.

Description

technical field [0001] The invention relates to an atmospheric experimental analysis instrument, in particular to an experimental analysis instrument for smog, which is applied in the technical fields of meteorological analysis and ecological atmospheric environment treatment. Background technique [0002] In recent years, smog weather has occurred more and more frequently, causing air quality to decline, deteriorating the ecological environment, and bringing greater harm and impact to human health and life. On the one hand, due to factors such as reduced visibility, smog has an important impact on road traffic, air transportation, power supply systems, and crop growth; on the other hand, it will invade the human body with breathing, causing respiratory system, cardiovascular system, Blood system, reproductive system and other diseases. Among the components of smog, solid particles account for a large proportion, are complex in composition, and are easy to carry germs. Afte...
